Some great links in here, you guys. That Richie Hawtin Slices docu is super good. And actually, any of the Slices ones are very good. Their technical discussions are fantastic.

So it's actually about house music (which is necessary for techno to exist of course) but I highly recommend Pump Up The Volume since it's a good, accurate history of how Detroit and Chicago became what they are.

A documentary I really like is 'better living through circuitry' from '99 which is about like techno and like raves, it's pretty cool and you can watch the entire thing on youtube. youtube com/watch?v=x4zN0v7C1mU
